Application filed December 16, 1898. semi No. 699,514. (No model.)

To all whom zit may concern.-

Beitknown that I, HARRY H.BnIne Arnn,

a resident of Akron, ,in the county of Summit nation of the molds, and 9is a rod which may be suitably interposed to determine the ro and Stateof Ohio, have invented certain new and useful Improvements in Machinesfor Molding Glassware; and I do hereby declare the following to beafull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

The invention relates to machines for form;

ing jars and other glassware and to that class which employdisconnectedmold-sections for successively formingpress and blow molds and arotating device forsuitably moving the sections to and from amold-bottom; and it has for its object to improve the mold-sectionmovingdevices and other parts.

The invention consists in the constructioni hereinafter described andpointed out. 7

In the accompanying drawings, Figure 1 is an elevation of the machine.Fig. 2 is a partial plan of a lock-operating device provided with acam-groove. Fig.3 is a perspective looking at the bottom of amold-section guideplate. Fig. 4 is a perspective of a mold-sectioncarriage. Fig. 5 is a perspective of'a mold-section-moving gear-ring andsupporting-ring carriage-gears. Fig. ,6 is a perspective of a cam-platefor moving; the mold-section carriages. Fig. 7 is asectionon line 77 ofFig. 9. Fig; 8.is a section on line 8-8 of Fig. 9; and Fig. 9 is a planof neck, body,

as when apress-mold is formed.

, Numeral 1 denotes a table, and 2 asupple mental top which ismaderotatable to carry the molds around step by step as required by thediflerent operations,'such as charging, pressing, and expanding. Theseparts are well known and need no particular description.

3 denotes a presser supported in a suitable frame having an adjustablebar 4. Bar-adjusting screws are indicated by 5, and 6 denotes adjustingnuts or sleeves which extend through the upper cross-bar of the frameand have sprocket-gears fixed thereto and are connected by a chain 7,whereby the turning of one sleeve or nut 6 rotates the other andindicated in Fig. 9. a concave face 12, constituting a half of a bodypress-mold, and'also a concave face 13,

the hub 19 of said frame.

moves the bar 4 in a right line, maintaining its exact relation tocontiguous parts.

8 denotes stops adjacent each operative sittary movement of thetablegtop2. A keeper or guide for the rod is denoted by 10, and 10 indicates ahead for the rod, said head having inclines and a stop-engaging notch atits highest'part wherelthe inclines meet.

The mold-sections 11 are made double, as Each section comprisesconstituting a half of afinishing or expansion mold. As illustrated inFig. 9, the sections are arranged with their faces 12 contiguous to forma press-mold, the expansion or blow =mold faces 13 being oppositelydisposed. The halves of either mold can be put in operative relation byasimultaneous half-rotation of the sections. The forming of differentmolds bymoving the section is effected by the handles 14: and 15, fixed,respectively, to the gear-ring 16 and cam-plate 17.

The ring 167rests on a circular frame 18, fixed to the supplementarytable-top 2, and is rotatable thereon. The cam-plate 17 is supported onthe central block 18" of the gearsupporting frame 18 and is rotatableabout The guide-plate 26 is situatedabove the cam-plate 17 and is fixedto frame 18 by means of screws passing through holes 26" in said plateand into tubes 18, fixed to frame 18. The guide-plate has fon its underside a supporting-rimwhich may be cut away, as at 26, for the passagehandle 15 of the cam-plate 17.

Each mold-section 11 is fixed to a carriage 21 in any suitable manner,as by screws passing through holes '25 in said carriage. Themold-sections and their carriages are situated above the guide-plate 26,which has guideslots 27, receiving each a post 28.0f a moldsectioncarriage. Said posts have each a part of the 29, adapted to slide in theWays SO-ingears 31.

The guide-plate 26 is fixed to table-top 2, and 26 denotes holes for thepurpose.

The rotation of the ring 16 rotates the gears 31 by means of thering-gears 32. The

said gears 31 turn about pivots 31, fixed in frame 18.

A suitable rotation of the cam-plate 17 moves the mold-sections to andfrom the centrally-situated bottom mold 33, said movement beingnecessarily radial,-because of the radial slots 27 in the fixedguide-plate.

The cam-plate has two grooves, each comprising a main part 34, adaptedto act upon a post 28 of a mold-section carriage 24 and,

in combination with a fixed guide 27, move said carriage radially, therotation of each carriage being simultaneously effected by theconnection of its foot 29 with a gear 31, said connection being suchthat the foot can slide in way 30, whereby the radial movement of thecarriage and mold-section is permitted while said gear-carriage andsection rotate with or about a pivot 31.

The cam-plate grooves each comprise a part 35, which is made concentricwith the campivot to permit a small initial inoperative movement of thecam-plate to permit the release of locking devices before thesectionmoving devices begin to operate.

41 are bars or rods sliding in suitable ways formed in the upper part ofhousings 42 and adapted to engage the mold-sections and hold.

them together when moved into an operative situation. The locking-barsare actuated by levers 40, which are turned upon their pivots by cams39, formed in ring 38. In operation when said ring and the cam-plate areoppositely moved to separate two mold-sections and bring their alternatefaces into operative relation, the parts being initially situated asindicated in Fig. 8, forexample, the cam-plate will be inoperative whilegrooves 35 are adjacent the carriage -posts 28, because said grooves areconcentric with the plate-pivot. This allows the cams 39 to operate andunlock the mold-sections before the cam-grooves 34E of cam-plate 17become operative and before they, in connection with other parts, beginto separate and rotate said sections.

43 denote neck-mold sections of usual form, and 44 are handles forrotating the table-top 2.

Having thus described my invention,what I claim as new,and desire tosecure by Letters Patent, is-

1. In a machiue'for molding glass, moldsections each comprisingtwooppositely-situated concavefaces of different dimensions and devicesfor successively bringing the similar faces of the sections in operativerelation for molding, said sections being separable and movable in rightlines.

2. In a machine for molding glass, moldsections each comprising twooppositely-situated concave faces of different dimensions and devicesfor successively bringing the similar faces of the sections in operativerelation for molding, said sections being separable and movable in rightlines, said devices comprising a rotating part mediately connected tothe disconnected sections.

3. In a machine for molding glass, moldsections each havingoppositely-situated halfmold faces, a rotating device adapted .toseparate such seetions,and a rotating device adapted to rotate thesections, said devices being independently operable.

4.
